This file lists a number of things that should be done to the library
in the future.
================================================================
* Automated tests for the following files:
- elib-node.el
- avltree.el
- bintree.el
- string.el
- read.el
- dll.el
- cookie.el
* Documentation of the automated test procedure
* Priority queue
* Debug variants of the container types which check everything on
run-time. This would be very slow but could also be a great help.
